Mojang. It's been several years now and you never bothered to fix the bedrock edition 2020 founders-cape-disappearing glitch.
People still care about it. Fix the glitch already — my goodness. The only way that people these days can have the cape is if they already have a skin that had the cape equipped before the glitch started. I'm one of those people. Personally, I'd like to have the choice to equip it to whatever skins I want and I don't want to have anxiety about it randomly getting deleted off my skins.
Just patch this already. Please. If you ignore this, I'll submit a thousand tickets on your ticketing site for this same issue as long as it means that it gets resolved. For myself and others.
If you do this, you will be banned from the bug tracker. As mentioned in the comment section of MCPE-103568, you will need to contact Minecraft Customer Support about this issue.
